Bipolar excitation of switched reluctance machines
"In recent years, the switched reluctance machine (SRM) has become a prominent electromechanical device and is seriously considered as a candidate for such diverse areas as: aerospace, vehicular technology, home appliances, and military applications. The resurgence of the SRM has primarily been the …

Doubly-Salient Permanent Magnet Flux-Reversal-Free-Stator Switched Reluctance Machines
A new hybrid machine having variable reluctance and permanent magnets (PMs) is presented. The machine makes use of the features of a PM machine and variable reluctance machine. The resulting machine is doubly salient and has a structure free of flux reversals. Unlike conventional doubly salient …

Design of Switched Reluctance Motors and Development of a Universal Controller for Switched Reluctance and Permanent Magnet Brushless DC Motor Drives
Switched Reluctance Machines (SRMs) are receiving significant attention from industries in the last decade. They are extremely inexpensive, reliable and weigh less than other machines of comparable power outputs. Although the design principles of the machine are available as a concatenation of many …

Position Sensorless Implementation for a Linear Switched Reluctance Machine
… sensorless position estimator for a 4.8 m Linear Switched Reluctance Machine (LSRM) with minimal modifications to the transducer-based controller is investigated for the first time in this study. LSRMs require position feedback for closed-loop control but present a low cost, high energy efficiency …
